Experiment on Diffusion (With Diagram)

Object: To demonstrate the phenomenon of diffusion. Requirements: Beaker, water, copper sulphate crystals. Method: Take a clean beaker and fill it completely with water. Place a big crystal of copper sulphate on one side of the beaker (Fig. 1). Observations: After some time, crystal of copper sulphate disappears and its particles get equally distributed throughout the water. Results: Molecules of [...]
